Membrane electrode composite layer for fuel cell, has connection region formed among layer and lower and upper frame portions, and filled with supplementary adhesive before partially bonding layer in frame portions

摘要

The layer (4) has a connection region (8) formed among the layer and lower and upper frame portions (1.1, 1.2), where the layer is partially bonded in the frame portions. The connection region is filled with a supplementary adhesive (3) before partially bonding the layer in the frame portions, where the supplementary adhesive seals the connection region against entry of water and gas. The connection region is heated after partially bonding the layer in the frame portions. A membrane (4.2) is arranged between two electrode layers (4.1). An independent claim is also included for a method for bonding a membrane electrode composite layer for a fuel cell in a frame.
